[detailed description of the invention]
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and the embodiments, the utility model is further elaborated.Should be appreciated that detailed description of the invention described herein only in order to explain the utility model, and be not used in restriction the utility model.
Below in conjunction with accompanying drawing, one detailed elaboration is done to specific embodiment of the utility model.
Please refer to Fig. 1, LED circuit board 100 of the present utility model, comprise circuit board 10, hot conduits 20, substrate 30, the LED light source 40 be electrically connected with substrate 30 and radiating subassembly 50.Circuit board 10 is attached at the surface of hot conduits 20, and can bend along the surface of hot conduits 20.Hot conduits 20 and radiating subassembly 50 are fixed together, the hot-fluid that LED light source 40 produces, and conduct to radiating subassembly 50 and dispel the heat, thus improve the radiating effect of system by hot conduits 20.
Incorporated by reference to Fig. 2, hot conduits 20 is the metal catheter of hollow, has cavity, and this cavity is built with working fluid 21 (as shown in Figure 5).By liquid vapour two phase change of working fluid 21 persistent loop, and vapour, the convection current that vapour returns toward liquid between the heat absorbing end and release end of heat of hot conduits of liquid fluid, enable the surface fast samming of hot conduits 20, improve the thermal conductivity of system.
Please consult Fig. 3 further, substrate 30 comprises end face and the bottom surface relative with this end face, and this bottom surface has line layer.LED light source 40 and this substrate 30 are electrically connected, and the bottom surface of substrate 30 fits in this circuit board 10.Substrate 30 realizes being electrically connected by the line layer of its bottom surface and circuit board 10.That is, LED light source 40 and circuit board 10 realize electrically conducting by substrate 30.A substrate 30 forms LED module with the LED light source 40 be fixed on this substrate 30.In order to ensure entirety can 360 degree luminous, the minimum number of LED module is 3 groups, and is evenly distributed on the surface of hot conduits 20.In other words, the angle between two adjacent LEDs module is 120 degree.In the present embodiment, the quantity of LED module is four, according to the position of circuit board 10, four LED modules are distributed in the periphery of hot conduits 20 equably, namely two adjacent LEDs module mutually vertically arrange and angle is 90 degree, thus launching of the uniform light that LED light source 40 is produced, improve the coverage of light, and then improve traffic safety.
